Be it known that l lhirni X lI 'U,Clt l zen of the United States residing at East Youngstown, in the county of Mahoning and. State of Ohio, have inventedcertain new and useful Improvements in Hair Clip pers, of which the following is a specification.

This invention relates to hairclippers, and has for its object the production of. an electrically driven, but manuallyoperated and guided, device for clipping hair from the human head. 7, s

Figure 1 of the drawings represents a top plan view. Figure 2 is an end View with the handle member partly broken away and in section. to disclose the mechanism housed therein, F igure 3 is an end elevationwith the casing removed. Figure dis a longitudinal sectional view of one end of the device. Figurefi is. a crcsssectional .view on line 5-5 Figure 6. Figure 6 is a front elevation with casing shown in section. Figure 7 is an outline of the teeth of the comb showing the different widths of. the teeth of the comb used as the operation progresses Figure 8 is a sectional view on line S-8 Figure 6.

Similar reference characters designate corresponding parts throughout the several figures of the drawings. Referring to the drawings, 11 represent oppositely disposed head pieces, which, together with the shafts mounted-therein as hereinafter specified, comprise what may be termed the framework of my device, and as the two ends of the device are in all respects duplicates, the specifications will be confined to one end and written in the singular number. I p f Rotatably mounted in the end piece 1 is the shaft 2. Rigidly attached to shaft 2, adjacent the inner face of the head piece 1. is the disk 3, to Which are attached a plurality of cutting bars 4:. Also rigidly attached to said shaft 2, outside of the head piece 1, is the grooved pulley p.

Also rotatably mounted in the head-piece 1 is the shaft 5 to which. is rigidly attached the grooved wheel or pulley 6 disposed in the recess 7 formed in the head piece 1. Also mounted upon said shaft 5 is the retracting coil spring 8, having its free end secured to the cross-bar 9.

1924. Serial No. 729,272.

Rigidly seemed to the outer face of head piece 1 is the forked bracket 10, each arm of whichhis provided with a central slot 11, within which is slidably mounted a headb'lock provided with a central opening which serves as a sliding journal for one end. of the counter-shaft 12. Rigidly mounted-upon said counter-shaft 12, and between the two arms of bracket 10, is the groovedpulley 13, while between the inner farm of, bracket 10 and the end piece 1 is the gearwheel 1a. I

The counter-shaft 12 is driven by belt 6 runningon pulleys Q) and 13.

. 15 represents a comb which is slidably secured to the lower face of the head-piece 1 bythe grooved flange 16 attached to the end, of the comb, and carrying the toothed rack 17 (Figure 3), and the compleinental grooved braCketlS. attached to the end piece 1. Attached to the back 19 of the comb 15 is a small loop 20, to which is secured one end of a flexible band 21 which passes around the small idle pulley 22 and has its opposite end secured to the grooved wheel .6 carriedby the rocker shaft 5, as hereinbefore explained.

23 represents the handle which is mounted upon the post 24; disposed in the loop 25 of the crossbar .9, and secured to the frame by the oppositely disposed holding arms 26 andrivets 27.

Enclosed withinthe hollow of the handle (see Figure 2) is a wire 10013.28 held normally in retracted position by coil spring 29. The uter end. of this loop is bent downwardly adjacentthe end of the handle (see 29 Figure l), and then at substantial ly right angles, running longitudinally with the machine (see 80) beyond the. outer face ofthe end piece 1, Where it. is again bent at substantially right. angles, and extends across-the outer face of the endpiecegl .(seeeBl), hasits upper end attached to v the counter-shaft 12 carrying the gear wheel 14. Firmly secured to the loop 28, and extending up through the slotted open ing 32 in the handle, is the knob or button 33. The curved arm 3e attached to the handle is designed merely as a finger rest or support for the convenience and support of the operator.

As already suggested and outlined in Figure 7, various width comb teeth may be used, the narrow one at the commencement, and increasing in width as the operation approaches the crown of the head.

It will be understood, of course, that shaft 2 is adapted to be driven by electricity through the medium of a flexible driving member attached to the shaft and leading to the source of power.

As a cover and protection for my device, and for the purpose of holding hair-clippings, I use a metal fiasing 35 formed in two sections, embracing the entire device and held in position by end caps 36. A door 87, hinged as at 38, is provided for the purpose of removing the clippings from the casing.

The operation of my device is as follows: 7 It is obvious that the comb 15 is held normally in an advanced position by the flexible band 21 attached to the pulley 6 rigidly mounted upon the spring controlled rocker shaft 5. When the operator desires to retract the comb, he presses the button 33 forward, thus forcing the loop 28 outwardly from the handle, and causing the gear 14 mounted upon the counter-shaft 12 to engage the toothed rack 17 on the flange 16 attached to the comb, thus driving the comb in the 0pposite direction against the resistance of spring 8, and when the operator releases the button 83, the gear 14: will become disengaged from the. rack 17, after which the comb will be immediately drawn back to normal position by the band 21.

I claim:

1. In a device of the character described, a frame-Work, a rotary cutting member mounted therein, means for driving said cutting member, a counter-shaft mounted upon said frame-work and carrying a gear wheel,means for driving said counter-shaft, a comb slidably mounted upon said framework and provided with a transverse toothed rack adapted to be engaged by said gear wheel, means for engaging and disengaging said wheel and rack, and means for holding said comb in normal position.

2. In a device of the character described, a frame-work, a rotary cutting member mounted therein and carrying a pulley, means for driving said cutting member, a countenshaft mounted upon the end of said frame-work and carrying a pulley and a gear wheel, a belt running upon said two pulleys, a comb slidably mounted upon said frame-work and provided with a transverse toothed rack adapted to be engaged by said gear wheel, means for engaging and disengaging said gear wheel and rack, and means for holding said comb in normal position.

3. In a device of the character described, a frame-work, a rotary cutting member mounted therein and carrying a pulley, means for driving said cutting melnlmr, a counter-shaft mounted upon the end of said frame-work and carrying a pulley and a gear wheel, a belt running upon said two pulleys, a comb slidably mounted upon said frame-work and provided with a transverse toothed rack adapted to be engaged by said gear wheel, means for engaging and disengaging said wheel and rack, a spring controlled rocking shaft carrying a pulley, and a. flexible connection between said pulley and said comb.

4:.
